Hi,

I would like to achieve the effect of smoke trails which are coming from the center of an explosion. I have already the explosion simulation. I tried by emitting from particles as you can see in the attached file, but I cant get them to look as good as this: http://img152.imageshack.us/img152/5454/sa6destructionff1.jpg [img152.imageshack.us]

any ideas or tips?

thanks in advance.

I did that before and could look for a sample file if you wish but the main process was that:

-create a particle system and emit a few particles to trace the path for every tentacle
-create a second particle system using the first one as a source to create trails
-freeze the trails on the last frame using timeshift
-create volumes for every trail using volume from attribute SOP and use those volumes as fuel in pyro combustion model
-use the particles from your first particle system as a source of temperature to ignite the fuel

thanks dobin for the reply, it will be great if you could find the sample file in order to study the basic setup. In my attached hip file I have done the steps 1 and 2 but I am emitting from the particles smoke. I would like to see how you do the rest of the steps.

cheers

here you go:

thanks a lot, I am gonna have a look and I will be back with more questions.
Just few more question related to volumes, whats the most important parameters (in rendering and shading) in order to have a high quality of fluid simulation and which renderer is the best to use PBR or Micro?
-How low can I go to the division size for the final simulation?

cheers
